AMD Radeon Pro WX 4100 vs NVIDIA GeForce GTX 750 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep in favor of the AMD Radeon Pro WX 4100 across all three head-to-head benchmark comparisons. The most dramatic margin appears in the Geekbench Metal test, where the AMD card scores 21,018 versus the NVIDIA GeForce GTX 750's 4,274. That is a 79.7% deficit for the older NVIDIA part, and it represents the single largest performance gap in the dataset.

The Geekbench OpenCL results tell a similar story, though with a slightly narrower spread. The Radeon Pro WX 4100 posts 17,642 points while the GeForce GTX 750 manages 9,315, a 47.2% difference. This indicates that even in a compute-oriented API that both cards support, the AMD architecture holds a substantial advantage. The Vulkan results sit between the two extremes: AMD scores 18,703 against NVIDIA's 8,078, a 56.8% gap.

What is notable is not just the direction of the wins but the consistency. The NVIDIA card fails to claim a single test. Looking at the broader database context, the GeForce GTX 750 sits at the 40th percentile among all GPUs with an average benchmark score of 7,222, while the Radeon Pro WX 4100 sits at the 37th percentile with an average of 6,330. This creates an interesting contradiction: the card with the higher percentile and higher average score loses every head-to-head test, while the card with the lower percentile wins all of them. The explanation likely lies in the weighting of different workloads across the full database, but within these specific comparisons, the AMD product is unambiguously faster.

The nearest rival data reinforces the individual standings of each card. The GTX 750's closest competitor is the AMD Radeon Vega 8 Mobile at 7,203, a mere 0.3% difference. The Radeon Pro WX 4100's nearest rival, the AMD Radeon R7 M350 at 6,327, is only 0.1% away. Both cards are tightly clustered among their peers, yet the gap between them in direct testing is enormous.

Architecture Differences

The two GPUs come from different manufacturing generations and design philosophies. The NVIDIA GeForce GTX 750 uses the GM107 chip built on the Maxwell architecture, fabricated by TSMC on a 28 nm process node. The AMD Radeon Pro WX 4100 uses the Baffin chip based on GCN 4.0, produced by GlobalFoundries on a 14 nm node. This process advantage is immediately visible in transistor density: AMD packs 24.4 million transistors per square millimeter versus NVIDIA's 12.6M per square millimeter. AMD's chip contains 3,000 million transistors on a 123 mm² die, while NVIDIA's contains 1,870 million on a larger 148 mm² die.

The compute resources differ substantially. The Radeon Pro WX 4100 features 1,024 shading units, 64 texture mapping units, and 16 ROPs. The GeForce GTX 750 has exactly half the shading units at 512, half the TMUs at 32, and the same 16 ROPs. Clock speeds also favor AMD: the Radeon Pro WX 4100 runs at a base of 1,125 MHz and boosts to 1,201 MHz, whereas the GTX 750 operates at 1,020 MHz base and 1,085 MHz boost. The combination of more execution units and higher clocks produces a theoretical FP32 throughput of 2.460 TFLOPS for AMD against 1,111.0 GFLOPS for NVIDIA. The AMD card also supports FP16 at a 1:1 ratio, while the GTX 750 has no listed FP16 capability.

Memory configurations show a generational shift. The Radeon Pro WX 4100 offers 4 GB of GDDR5 on a 128-bit bus with 96.00 GB/s of bandwidth. The GeForce GTX 750 offers only 1 GB of GDDR5 on the same 128-bit bus, yielding 80.19 GB/s. The interface also differs: NVIDIA uses PCIe 3.0 x16 while AMD uses PCIe 3.0 x8, though the practical impact of this bandwidth difference is not captured in the provided benchmark data.

Display outputs reflect their intended markets. The GTX 750 provides 2x DVI and 1x mini-HDMI 1.4a, while the Radeon Pro WX 4100 provides 4x mini-DisplayPort 1.4a. API support also diverges: the AMD card supports DirectX 12 (12_0) and Vulkan 1.3, while the NVIDIA card supports DirectX 12 (11_0) and Vulkan 1.4. Both support OpenGL 4.6.

Where Each One Wins

Given the head-to-head results, the Radeon Pro WX 4100 wins in every measured category. The question is what those categories represent for real-world usage. The Metal score of 21,018 suggests strong performance in Apple ecosystem applications that leverage Metal, a workload the GTX 750 cannot meaningfully contest given its 4,274 result. The OpenCL score of 17,642 versus 9,315 indicates the AMD card handles general-purpose GPU compute substantially better, which matters for rendering, simulation, and productivity tasks. The Vulkan score of 18,703 versus 8,078 points to superior performance in modern cross-platform graphics APIs.

The GTX 750's sole advantage appears to be its position within its own peer group. Its average benchmark score of 7,222 places it in the 40th percentile, above the Radeon Pro WX 4100's 37th percentile. The nearest rival data shows the GTX 750 edging out the GeForce GTX 970 by 0.9%, a surprising result given the GTX 970's higher tier in NVIDIA's lineup. The Radeon Pro WX 4100, by contrast, trails the GeForce GTX 460 SE and GTX 580M by 0.9% in average score.

The Radeon Pro WX 4100 also benefits from double the memory capacity at 4 GB versus 1 GB, which matters for larger textures, datasets, and multi-display configurations. Its four mini-DisplayPort outputs support more simultaneous displays than the GTX 750's dual DVI and single mini-HDMI combination. The AMD card achieves this with a lower TDP of 50 W against NVIDIA's 55 W, and both require only a 250 W suggested power supply with no external power connectors.

The Verdict

The data points to a clear conclusion: the AMD Radeon Pro WX 4100 is the faster card in every measured benchmark, with margins ranging from 47.2% to 79.7% across Metal, OpenCL, and Vulkan. Its doubling of shading units, higher clocks, larger memory pool, and more modern process node all contribute to this outcome. The NVIDIA GeForce GTX 750's higher average benchmark score and better percentile ranking reflect its position among a different set of peers, but that does not translate into any head-to-head victory.

For workloads built around Metal, OpenCL, or Vulkan, the Radeon Pro WX 4100 is the only rational choice based on the recorded data. Its four DisplayPort outputs and 4 GB memory capacity also make it more suitable for multi-display professional setups. The GTX 750 offers no measured advantage in any shared test, so its appeal rests entirely on its lower launch MSRP and its favorable standing relative to its own nearest rivals, which include the GeForce GTX 970 at a 0.9% gap.

The verdict is straightforward: the Radeon Pro WX 4100 wins on raw performance across all three APIs, while the GeForce GTX 750 holds a statistical edge only in its aggregate database ranking. Buyers prioritizing benchmark results should choose the AMD card. Those constrained to the GTX 750's era or price tier may still find it competitive against its immediate peers, but against the Radeon Pro WX 4100, the performance differential is too large to ignore.
